Hi,
I created a driver for lots of APPA-based devices for sigrok this weekend. This includes Multimeters and Clamp Multimeters with USB/Serial and Bluetooth LE.
Currently the driver supports the BENNING MM 12, BENNING CM 12, Sefram 7352B, APPA 506(B), 208(B), 155B, 156B, 157B, 158B and a couple of others under all kinds of brands.
I implemented and tested it with a BENNING MM 12 (APPA 506B). Functions for the other meters with the same communication protocol are implemented, but obviously untested, since I don't have the hardware.
Currently all live reading functions for USB/Serial/BLE are implemented, but log download and calibration will follow when I have the time.
Sigrok-Wikipage for the meter I used, including some pictures:
https://sigrok.org/wiki/BENNING_MM_12So if anyone here has one of those APPA 150/208/506 based meters, regardless of the brand, I would be happy about any tests with the new sigrok driver.
Here's my github-fork of libsigrok containing the driver "appa-b":
https://github.com/Cymaphore/libsigrokThe driver is currently under review and will be included with mainline sigrok once it passed.
Thanks and best regards,
Martin
